Qusetion about power system and MATLAB

2) Write MATLAB m-file which generates VQ curves for the system in Fig. 1 with parameters E = 1.05, X = 0.75, unity power factor for the following cases of P/P,nar (a) P/Pmar0.9; (b) P/P,naz= 0.7; (c) P/Pmar0.6 E2 where Pmar is the maximum power transfer at unity power factor (recall. Pmaz- ). Find operating point at each case ('stable' intersection with line Qc 0). For each case deter- mine the amount of shunt compensation needed to obtain voltage of V1 pu (use Data Cursor button). Fill your results in the Table 3. Note: Since all variables are given in pu there is no need for normalization of your axis when you plot curves.
